Add a static field

translate

public void translate()

Translate the stylesheet into JVM bytecodes.

compileStaticInitializer

private void compileStaticInitializer(ClassGenerator classGen)

Compile the namesArray, urisArray, typesArray, namespaceArray, namespaceAncestorsArray, prefixURIsIdxArray and prefixURIPairsArray into the static initializer. They are read-only from the translet. All translet instances can share a single copy of this informtion.

The namespaceAncestorsArray, prefixURIsIdxArray and prefixURIPairsArray contain namespace information accessible from the stylesheet:

namespaceAncestorsArray

Array indexed by integer stylesheet node IDs containing node IDs of the nearest ancestor node in the stylesheet with namespace declarations or -1 if there is no such ancestor. There can be more than one disjoint tree of nodes - one for each stylesheet module

prefixURIsIdxArray

Array indexed by integer stylesheet node IDs containing the index into prefixURIPairsArray of the first namespace prefix declared for the node. The values are stored in ascending order, so the next value in this array (if any) can be used to find the last such prefix-URI pair

prefixURIPairsArray

Array of pairs of namespace prefixes and URIs. A zero-length string represents the default namespace if it appears as a prefix and a namespace undeclaration if it appears as a URI.

For this stylesheet

 <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
   <xsl:template match="/">
     <xsl:for-each select="*" xmlns:foo="foouri">
       <xsl:element name="{n}" xmlns:foo="baruri">
     </xsl:for-each>
     <out xmlns="lumpit"/>
     <xsl:element name="{n}" xmlns="foouri"/>
     <xsl:element name="{n}" namespace="{ns}" xmlns="limpit"/gt;
   </xsl:template>
 </xsl:stylesheet>
 

there will be four stylesheet nodes whose namespace information is needed, and

• namespaceAncestorsArray will have the value [-1,0,1,0];
• prefixURIsIdxArray will have the value [0,4,6,8]; and
• prefixURIPairsArray will have the value ["xml","http://www.w3.org/XML/1998/namespace", "xsl","http://www.w3.org/1999/XSL/Transform" "foo","foouri","foo","baruri","","foouri"].

compileConstructor

private void compileConstructor(ClassGenerator classGen,
                                Output output)

Compile the translet's constructor

compileTopLevel

private java.lang.String compileTopLevel(ClassGenerator classGen)

Compile a topLevel() method into the output class. This method is called from transform() to handle all non-template top-level elements. Returns the signature of the topLevel() method. Global variables/params and keys are first sorted to resolve dependencies between them. The XSLT 1.0 spec does not allow a key to depend on a variable. However, for compatibility with Xalan interpretive, that type of dependency is allowed. Note also that the buildKeys() method is still generated as it is used by the LoadDocument class, but it no longer called from transform().

resolveDependencies

private java.util.Vector resolveDependencies(java.util.Vector input)

This method returns a vector with variables/params and keys in the order in which they are to be compiled for initialization. The order is determined by analyzing the dependencies between them. The XSLT 1.0 spec does not allow a key to depend on a variable. However, for compatibility with Xalan interpretive, that type of dependency is allowed and, therefore, consider to determine the partial order.

compileBuildKeys

private java.lang.String compileBuildKeys(ClassGenerator classGen)

Compile a buildKeys() method into the output class. Note that keys for the input document are created in topLevel(), not in this method. However, we still need this method to create keys for documents loaded via the XPath document() function.

compileTransform

private void compileTransform(ClassGenerator classGen)

Compile transform() into the output class. This method is used to initialize global variables and global parameters. The current node is set to be the document's root node.

peepHoleOptimization

private void peepHoleOptimization(MethodGenerator methodGen)

Peephole optimization: Remove sequences of [ALOAD, POP].

addParam

public int addParam(Param param)

addVariable

public int addVariable(Variable global)

display

public void display(int indent)

Description copied from class: SyntaxTreeNode

Displays the contents of this syntax tree node (to stdout). This method is intended for debugging _only_, and should be overridden by all syntax tree node implementations.

Overrides:

display in class SyntaxTreeNode

Parameters:

indent - Indentation level for syntax tree levels.

getAllValidTemplates

public java.util.Vector getAllValidTemplates()
