Method Detail

getFunctionArgsString

public static final java.lang.String getFunctionArgsString(org.mozilla.javascript.ast.FunctionNode fn)

Iterates through a function's parameters and returns a string representation of them, suitable for presentation as part of the method's signature.

Parameters:

fn - The function node.

Returns:

The string representation of the function's arguments.

getPropertyName

public static final java.lang.String getPropertyName(org.mozilla.javascript.ast.AstNode propKeyNode)

Property keys in object literals can be identifiers or string literals. This method takes an AST node that was the key of an ObjectProperty and returns its value, no matter what the concrete AST node's type.

Parameters:

propKeyNode - The AST node for the property key.

Returns:

The property key's value.

getPrototypeClazz

public static final java.lang.String getPrototypeClazz(java.util.List<org.mozilla.javascript.ast.AstNode> nodes)

getPrototypeClazz

public static final java.lang.String getPrototypeClazz(java.util.List<org.mozilla.javascript.ast.AstNode> nodes,
                                                       int depth)

isPrototypeNameNode

public static final boolean isPrototypeNameNode(org.mozilla.javascript.ast.AstNode node)

isPrototypePropertyGet

public static final boolean isPrototypePropertyGet(org.mozilla.javascript.ast.PropertyGet pg)

isSimplePropertyGet

public static final boolean isSimplePropertyGet(org.mozilla.javascript.ast.PropertyGet pg,
                                                java.lang.String expectedObj,
                                                java.lang.String expectedField)

Returns whether a PropertyGet is a simple one, referencing an object's value 1 level deep. For example, Object.create.

Parameters:

pg - The PropertyGet.

expectedObj - The expected object value.

expectedField - The expected string value.

Returns:

Whether the object is what was expected.
