Constructor Summary

RewriteRuleTokenStream(TreeAdaptor adaptor, java.lang.String elementDescription)

RewriteRuleTokenStream(TreeAdaptor adaptor, java.lang.String elementDescription, java.util.List elements)
Create a stream, but feed off an existing list

RewriteRuleTokenStream(TreeAdaptor adaptor, java.lang.String elementDescription, java.lang.Object oneElement)
Create a stream with one element

Method Summary

protected java.lang.Object	dup(java.lang.Object el) When constructing trees, sometimes we need to dup a token or AST subtree.
protected java.lang.Object	toTree(java.lang.Object el) Ensure stream emits trees; tokens must be converted to AST nodes.

Method Detail

toTree

protected java.lang.Object toTree(java.lang.Object el)

Description copied from class: RewriteRuleElementStream

Ensure stream emits trees; tokens must be converted to AST nodes. AST nodes can be passed through unmolested.

Overrides:

toTree in class RewriteRuleElementStream

dup

protected java.lang.Object dup(java.lang.Object el)

Description copied from class: RewriteRuleElementStream

When constructing trees, sometimes we need to dup a token or AST subtree. Dup'ing a token means just creating another AST node around it. For trees, you must call the adaptor.dupTree().
