Class TransformSnapshotImpl

java.lang.Object
  org.apache.xalan.transformer.TransformSnapshotImpl

All Implemented Interfaces:

TransformSnapshot

Deprecated. It doesn't look like this code, which is for tooling, has functioned propery for a while, so it doesn't look like it is being used.

 class TransformSnapshotImpl
extends java.lang.Object
implements TransformSnapshot

This class holds a "snapshot" of it's current transformer state, which can later be restored. This only saves state which can change over the course of the side-effect-free (i.e. no extensions that call setURIResolver, etc.).

Field Summary

Field Detail

m_variableStacks

private VariableStack m_variableStacks

Deprecated.

The stack of Variable stack frames.

m_currentNodes

private IntStack m_currentNodes

Deprecated.

The stack of current node objects. Not to be confused with the current node list.

m_currentExpressionNodes

private IntStack m_currentExpressionNodes

Deprecated.

A stack of the current sub-expression nodes.

m_contextNodeLists

private java.util.Stack m_contextNodeLists

Deprecated.

The current context node lists stack.

m_contextNodeList

private DTMIterator m_contextNodeList

Deprecated.

The current context node list.

m_axesIteratorStack

private java.util.Stack m_axesIteratorStack

Deprecated.

Stack of AxesIterators.

m_currentTemplateRuleIsNull

private BoolStack m_currentTemplateRuleIsNull

Deprecated.

Is > 0 when we're processing a for-each.

m_currentTemplateElements

private ObjectStack m_currentTemplateElements

Deprecated.

A node vector used as a stack to track the current ElemTemplateElement. Needed for the org.apache.xalan.transformer.TransformState interface, so a tool can discover the calling template.

m_currentMatchTemplates

private java.util.Stack m_currentMatchTemplates

Deprecated.

A node vector used as a stack to track the current ElemTemplate that was matched, as well as the node that was matched. Needed for the org.apache.xalan.transformer.TransformState interface, so a tool can discover the matched template, and matched node.

m_currentMatchNodes

private NodeVector m_currentMatchNodes

Deprecated.

A node vector used as a stack to track the current ElemTemplate that was matched, as well as the node that was matched. Needed for the org.apache.xalan.transformer.TransformState interface, so a tool can discover the matched template, and matched node.

m_countersTable

private CountersTable m_countersTable

Deprecated.

The table of counters for xsl:number support.

m_nsContextPushed

boolean m_nsContextPushed

Deprecated.

Indicate whether a namespace context was pushed

m_nsSupport

private NamespaceMappings m_nsSupport

Constructor Detail

TransformSnapshotImpl

TransformSnapshotImpl(TransformerImpl transformer)

Deprecated. It doesn't look like this code, which is for tooling, has functioned propery for a while, so it doesn't look like it is being used.

Constructor TransformSnapshotImpl Take a snapshot of the currently executing context.

Parameters:

transformer - Non null transformer instance

Method Detail

apply

void apply(TransformerImpl transformer)

Deprecated. It doesn't look like this code, which is for tooling, has functioned propery for a while, so it doesn't look like it is being used.

This will reset the stylesheet to a given execution context based on some previously taken snapshot where we can then start execution

Parameters:

transformer - Non null transformer instance
