Method Detail

isCheap

public final boolean isCheap()

Description copied from class: CodeChunk.WithValue

Returns true if the expression represented by this code chunk is so trivial that it isn't worth storing it in a temporary if it needs to be referenced multiple times.

The default is false, only certain special code chunks return true.

Overrides:

isCheap in class CodeChunk.WithValue

collectRequires

public void collectRequires(CodeChunk.RequiresCollector collector)

Description copied from class: CodeChunk

Adds all the 'goog.require' identifiers needed by this CodeChunk to the given collection.

Specified by:

collectRequires in class CodeChunk

singleExprOrName

public JsExpr singleExprOrName()

Description copied from class: CodeChunk.WithValue

If this chunk can be represented as a single expression, returns that expression. If this chunk cannot be represented as a single expression, returns an expression containing references to a variable defined by the corresponding initial statements.

This method should rarely be used, but is needed when interoperating with parts of the codegen system that do not yet understand CodeChunks (e.g. SoyJsSrcFunction).

Specified by:

singleExprOrName in class CodeChunk.WithValue
