Class CodeChunk.Generator

java.lang.Object

com.google.template.soy.jssrc.dsl.CodeChunk.Generator

Enclosing class:

CodeChunk

public static final class CodeChunk.Generator
extends Object

Code chunks in a single Soy template emit code into a shared JavaScript lexical scope, so they must use distinct variable names. This class enforces that.

Method Summary

Modifier and Type	Method and Description
CodeChunk.WithValue	conditionalExpression(CodeChunk.WithValue predicate, CodeChunk.WithValue consequent, CodeChunk.WithValue alternate) Returns a code chunk representing an if-then-else condition.
static CodeChunk.Generator	create(UniqueNameGenerator nameGenerator) Returns an object that can be used to build code chunks.

Method Detail

create

public static CodeChunk.Generator create(UniqueNameGenerator nameGenerator)

Returns an object that can be used to build code chunks.

declarationBuilder

public VariableDeclaration.Builder declarationBuilder()

Creates a code chunk declaring an automatically-named variable with no initializer.

conditionalExpression

public CodeChunk.WithValue conditionalExpression(CodeChunk.WithValue predicate,
                                                 CodeChunk.WithValue consequent,
                                                 CodeChunk.WithValue alternate)

Returns a code chunk representing an if-then-else condition.

If all the parameters are representable as single expressions, the returned chunk will use the JavaScript ternary syntax (predicate ? consequent : alternate). Otherwise, the returned chunk will use JavaScript conditional statement syntax: var $tmp = null; if (predicate) { $tmp = consequent; } else { $tmp = alternate; }
