Method Detail

getResult

public AstNode getResult()

Returns result expression node (just after opening bracket)

setResult

public void setResult(AstNode result)

Sets result expression, and sets its parent to this node.

Throws:

java.lang.IllegalArgumentException - if result is null

getLoops

public java.util.List<ArrayComprehensionLoop> getLoops()

Returns loop list

setLoops

public void setLoops(java.util.List<ArrayComprehensionLoop> loops)

Sets loop list

Throws:

java.lang.IllegalArgumentException - if loops is null

addLoop

public void addLoop(ArrayComprehensionLoop acl)

Adds a child loop node, and sets its parent to this node.

Throws:

java.lang.IllegalArgumentException - if acl is null

getFilter

public AstNode getFilter()

Returns filter expression, or null if not present

setFilter

public void setFilter(AstNode filter)

Sets filter expression, and sets its parent to this node. Can be null.

getIfPosition

public int getIfPosition()

Returns position of 'if' keyword, -1 if not present

setIfPosition

public void setIfPosition(int ifPosition)

Sets position of 'if' keyword

getFilterLp

public int getFilterLp()

Returns filter left paren position, or -1 if no filter

setFilterLp

public void setFilterLp(int lp)

Sets filter left paren position, or -1 if no filter

getFilterRp

public int getFilterRp()

Returns filter right paren position, or -1 if no filter

setFilterRp

public void setFilterRp(int rp)

Sets filter right paren position, or -1 if no filter

toSource

public java.lang.String toSource(int depth)

Description copied from class: AstNode

Emits source code for this node. Callee is responsible for calling this function recursively on children, incrementing indent as appropriate.

Note: if the parser was in error-recovery mode, some AST nodes may have null children that are expected to be non-null when no errors are present. In this situation, the behavior of the toSource method is undefined: toSource implementations may assume that the AST node is error-free, since it is intended to be invoked only at runtime after a successful parse.

Overrides:

toSource in class Scope

Parameters:

depth - the current recursion depth, typically beginning at 0 when called on the root node.

visit

public void visit(NodeVisitor v)

Visits this node, the result expression, the loops, and the optional filter.

Overrides:

visit in class Scope

Parameters:

v - the object to call with this node and its children
