Constructor Detail

StreamNode

public StreamNode(java.lang.String streamText,
          java.lang.String streamName,
          java.util.List<ModuleNode> moduleNodes,
          SourceChannelNode sourceChannelNode,
          SinkChannelNode sinkChannelNode)

Method Detail

stringify

public java.lang.String stringify(boolean includePositionalInfo)

Specified by:

stringify in class AstNode

Returns:

a string representation of the AST. Useful for debugging/testing.

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

getModuleNodes

public java.util.List<ModuleNode> getModuleNodes()

getSourceChannelNode

public SourceChannelNode getSourceChannelNode()

getSinkChannelNode

public SinkChannelNode getSinkChannelNode()

getStreamName

public java.lang.String getStreamName()

getModule

public ModuleNode getModule(java.lang.String moduleName)

Find the first reference to the named module in the stream. If the same module is referred to multiple times the secondary references cannot be accessed via this method.

Returns:

the first occurrence of the named module in the stream

resolve

public void resolve(StreamLookupEnvironment env,
           java.lang.String expressionString)

getIndexOfLabel

public int getIndexOfLabel(java.lang.String labelOrModuleName)

getStreamData

public java.lang.String getStreamData()

getStreamText

public java.lang.String getStreamText()

getName

public java.lang.String getName()
