Constructor Detail

TemplateRuleEE

public TemplateRuleEE()

Create a template rule

Method Detail

setDeclaredStreamable

public void setDeclaredStreamable(boolean streamable)

Say whether or not this template is declared as streamable

Overrides:

setDeclaredStreamable in class TemplateRule

Parameters:

streamable - true if the template belongs to a streamable mode; set to false if it does not belong to a streamable mode, or if it is found that the template is not actually streamable, and fallback to non-streaming has been requested.

isDeclaredStreamable

public boolean isDeclaredStreamable()

Ask whether or not this template is declared as streamable

Overrides:

isDeclaredStreamable in class TemplateRule

Returns:

true if the template belongs to a streamable mode; false if it does not belong to a streamable mode, or if it is found that the template is not actually streamable, and fallback to non-streaming has been requested.

setInitializer

public void setInitializer(TemplateRuleInitializer initializer)

getInitializer

public TemplateRuleInitializer getInitializer()

prepareInitializer

public void prepareInitializer(Compilation compilation,
                               ComponentDeclaration decl)

Prepare for JIT compilation.

Overrides:

prepareInitializer in class TemplateRule

Parameters:

compilation - the XSLT compilation

decl - the component declaration of this template rule

initialize

public void initialize()
                throws XPathException

Ensure that any first-time initialization has been done. Used in Saxon-EE to do JIT compilation

Overrides:

initialize in class TemplateRule

Throws:

XPathException - if any error occurs

isActuallyStreamable

public boolean isActuallyStreamable(java.util.List<java.lang.String> reasons)

Ask whether this template satisfies the rules for a guaranteed streamable template

Parameters:

reasons - the caller may supply a list which on return will contain explanations for why the template is not streamable, suitable for inclusion in error messages

Returns:

true if the template is within the (Saxon or W3C) definition of guaranteed streamable

makeInversion

public void makeInversion()
                   throws XPathException

Generate the inversion of the expression comprising the body of a template rules. Supported in Saxon-EE only

Throws:

XPathException

getInversion

public ComponentInversion getInversion()
                                throws XPathException

Throws:

XPathException
