Class CompilerInfo

java.lang.Object

net.sf.saxon.trans.CompilerInfo

public class CompilerInfo
extends java.lang.Object

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.

Constructor Detail

CompilerInfo

public CompilerInfo(Configuration config)

Create an empty CompilerInfo object with default settings. (Note, this does not copy settings from the defaultXsltCompilerInfo held by the configuration. For that, use new CompilerInfo(config.getDefaultXsltCompilerInfo()).

Create a CompilerInfo object as a copy of another CompilerInfo object

Parameters:

info - the existing CompilerInfo object

setURIResolver

public void setURIResolver(javax.xml.transform.URIResolver resolver)

setParameter

public void setParameter(StructuredQName name,
                         Sequence seq)

Set the value of a stylesheet parameter. Static (compile-time) parameters must be provided using this method on the XsltCompiler object, prior to stylesheet compilation. Non-static parameters may also be provided using this method if their values will not vary from one transformation to another. No error occurs at this stage if the parameter is unknown, or if the value is incorrect for the parameter. Setting a value for a parameter overwrites any previous value set for the same parameter.

Parameters:

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

Parameters:

Since:

9.2

Returns:

the current policy.

Since:

9.2

isVersionWarning

public boolean isVersionWarning()

Deprecated. since 9.8.0.2. Always now returns false. See bug 3278.

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)

Deprecated. since 9.8.0.2. The method no longer has any effect. See bug 3278.

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

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:

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:

Since:

9.3

setXsltVersion

public void setXsltVersion(int version)

Deprecated. since Saxon 9.8 (has no effect).

Set the version of XSLT to be supported by this processor. From Saxon 9.8 this has no effect; the processor will always be an XSLT 3.0 processor.

Parameters:

version - The decimal version number times ten, for example 30 indicates XSLT 3.0.

Since:

9.3. Changed in 9.7 to take an integer rather than a decimal. Ignored from 9.8.

Get the version of XSLT requested for this compilation.

Returns:

30 (for XSLT 3.0)

setExtensionFunctionLibrary

public void setExtensionFunctionLibrary(FunctionLibrary library)

Deprecated. since 9.7. Any extension function library set using this mechanism will not be available if the package is saved and reloaded.

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()
