Class CompilerInfo

java.lang.Object
  net.sf.saxon.trans.CompilerInfo

All Implemented Interfaces:

Serializable

public class CompilerInfo
extends Object
implements Serializable

This class exists to hold information associated with a specific XSLT compilation episode. In JAXP, the URIResolver and ErrorListener used during XSLT compilation are those defined in the TransformerFactory. The .NET API and the s9api API, however, allow finer granularity, and this class exists to support that.

setCodeInjector

public void setCodeInjector(CodeInjector injector)

Set whether trace hooks are to be included in the compiled code. To use tracing, it is necessary both to compile the code with trace hooks included, and to supply a TraceListener at run-time

Parameters:

injector - the code injector used to insert trace or debugging hooks, or null to clear any existing entry

Since:

9.4

getCodeInjector

public CodeInjector getCodeInjector()

Get the registered CodeInjector, if any

true if trace hooks are included, false if not.

Since:

8.9

setRecoveryPolicy

public void setRecoveryPolicy(int policy)

Set the policy for handling recoverable errrors. Note that for some errors the decision can be made at run-time, but for the "ambiguous template match" error, the decision is (since 9.2) fixed at compile time.

Parameters:

policy - the recovery policy to be used. The options are Configuration.RECOVER_SILENTLY, Configuration.RECOVER_WITH_WARNINGS, or Configuration.DO_NOT_RECOVER.

Since:

9.2

getRecoveryPolicy

public int getRecoveryPolicy()

Get the policy for handling recoverable errors. Note that for some errors the decision can be made at run-time, but for the "ambiguous template match" error, the decision is (since 9.2) fixed at compile time.

Returns:

the current policy.

Since:

9.2

isVersionWarning

public boolean isVersionWarning()

Ask whether a warning is to be output when the stylesheet version does not match the processor version. In the case of stylesheet version="1.0", the XSLT specification requires such a warning unless the user disables it.

Returns:

true if these messages are to be output.

Since:

9.2

setVersionWarning

public void setVersionWarning(boolean warn)

Say whether a warning is to be output when the stylesheet version does not match the processor version. In the case of stylesheet version="1.0", the XSLT specification requires such a warning unless the user disables it.

Parameters:

warn - true if these messages are to be output.

Since:

9.2

setSchemaAware

public void setSchemaAware(boolean schemaAware)

Say that the stylesheet must be compiled to be schema-aware, even if it contains no xsl:import-schema declarations. Normally a stylesheet is treated as schema-aware only if it contains one or more xsl:import-schema declarations. If it is not schema-aware, then all input documents must be untyped, and validation of temporary trees is disallowed (though validation of the final result tree is permitted). Setting the argument to true means that schema-aware code will be compiled regardless.

Parameters:

schemaAware - If true, the stylesheet will be compiled with schema-awareness enabled even if it contains no xsl:import-schema declarations. If false, the stylesheet is treated as schema-aware only if it contains one or more xsl:import-schema declarations

Since:

9.2

isSchemaAware

public boolean isSchemaAware()

Ask whether schema-awareness has been requested by means of a call on setSchemaAware(boolean)

Returns:

true if schema-awareness has been requested

setDefaultInitialTemplate

public void setDefaultInitialTemplate(StructuredQName initialTemplate)

Set the default initial template name for a stylesheet compiled using this CompilerInfo. This is only a default; it can be overridden when the stylesheet is executed

Parameters:

initialTemplate - the name of the default initial template, or null if there is no default. No error occurs (until run-time) if the stylesheet does not contain a template with this name.

Since:

9.3

getDefaultInitialTemplate

public StructuredQName getDefaultInitialTemplate()

Get the default initial template name for a stylesheet compiled using this CompilerInfo. This is only a default; it can be overridden when the stylesheet is executed

Returns:

the name of the default initial template, or null if there is no default, as set using setDefaultInitialTemplate(net.sf.saxon.om.StructuredQName)

Since:

9.3

setDefaultInitialMode

public void setDefaultInitialMode(StructuredQName initialMode)

Set the default initial mode name for a stylesheet compiled using this CompilerInfo. This is only a default; it can be overridden when the stylesheet is executed

Parameters:

initialMode - the name of the default initial mode, or null if there is no default. No error occurs (until run-time) if the stylesheet does not contain a mode with this name.

Since:

9.3

getDefaultInitialMode

public StructuredQName getDefaultInitialMode()

Get the default initial mode name for a stylesheet compiled using this CompilerInfo. This is only a default; it can be overridden when the stylesheet is executed

Returns:

the name of the default initial mode, or null if there is no default, as set using setDefaultInitialMode(net.sf.saxon.om.StructuredQName)

Since:

9.3

setXsltVersion

public void setXsltVersion(DecimalValue version)

Set the version of XSLT to be supported by this processor. This determines the version of the XSLT specification to which the processor conforms. This does not have to match the version attribute in the stylesheet; for example if the processor version is 2.0 and the stylesheet is version 3.0, then the stylesheet will be processed using the rules for a 2.0 processor in forwards compatibility mode, rather than the rules for a 3.01 processor.

The value 0.0 (which is the default) indicates that the processor version is to be taken from the version attribute of the xsl:stylesheet element.

XSLT 2.1 features are supported only in Saxon-EE. Setting the version to 3.0 here will not fail if the wrong edition is in use, but use of XSLT 3.0 features will fail subsequently.

Parameters:

version - must be numerically equal to 0.0, 2.0 or 3.0

Throws:

IllegalArgumentException - if the version is invalid

Since:

9.3

getXsltVersion

public DecimalValue getXsltVersion()

Get the version of XSLT supported by this processor

Returns:

DecimalValue.TWO or DecimalValue.THREE, or zero indicating that the processor versino is taken from the version attribute of the xsl:stylesheet element.)

Since:

9.3

setExtensionFunctionLibrary

public void setExtensionFunctionLibrary(FunctionLibrary library)

Set a library of extension functions. The functions in this library will be available in all modules of the stylesheet. The function library will be searched after language-defined libraries (such as built-in functions, user-defined XQuery functions, and constructor functions) but before extension functions defined at the Configuration level.

Parameters:

library - the function library to be added (replacing any that has previously been set). May be null to clear a previously-set library

Since:

9.4

getExtensionFunctionLibrary

public FunctionLibrary getExtensionFunctionLibrary()

Get any function library that was previously set using setExtensionFunctionLibrary(net.sf.saxon.functions.FunctionLibrary).

Returns:

the extension function library, or null if none has been set.

Since:

9.4
