Field Detail

targetImportNode

protected ExpressionNodeBase targetImportNode

Package to import

importKind

protected IImportNode.ImportKind importKind

Constructor Detail

ImportNode

public ImportNode(ExpressionNodeBase targetImportNode)

Constructor.

Parameters:

targetImportNode - package to import

Method Detail

buildImportNode

public static ImportNode buildImportNode(String qname)

Builds an ImportNode for a qname.

makeWildcardName

public static String makeWildcardName(String name)

Turns a qualified name such as "flash.display.Sprite" into a wildcard name like "flash.display.*".

getNodeID

public ASTNodeID getNodeID()

Description copied from interface: IASNode

Get the opcode of this node

Specified by:

getNodeID in interface IASNode

Returns:

the opcode - this is one of the constants defined in ASTConstants

getChildCount

public int getChildCount()

Description copied from interface: IASNode

Get the number of children

Specified by:

getChildCount in interface IASNode

Overrides:

getChildCount in class NodeBase

Returns:

the number of children

getChild

public IASNode getChild(int i)

Description copied from interface: IASNode

Get a particular child of this node

Specified by:

getChild in interface IASNode

Overrides:

getChild in class NodeBase

Parameters:

i - the child's index

Returns:

the specified child

setChildren

protected void setChildren(boolean fillInOffsets)

Description copied from class: NodeBase

If this node has custom children (names, arguments, etc), shove them into the list of children. Used during parsing.

Overrides:

setChildren in class NodeBase

normalize

public void normalize(boolean fillInOffsets)

Description copied from class: NodeBase

Normalize the tree. Move custom children into the real child list and fill in missing offsets so that offset lookup will work. Used during parsing.

Overrides:

normalize in class NodeBase

analyze

protected void analyze(EnumSet<PostProcessStep> set,
           ASScope scope,
           Collection<ICompilerProblem> problems)

Overrides:

analyze in class NodeBase

buildInnerString

protected boolean buildInnerString(StringBuilder sb)

Description copied from class: NodeBase

For debugging only. This method is called by buildOuterString(). It is overridden by subclasses to display optional node-specific information in the middle of the string, between the node type and the location information.

Overrides:

buildInnerString in class NodeBase

getImportKind

public IImportNode.ImportKind getImportKind()

Description copied from interface: IImportNode

Returns the type that this import represents

Specified by:

getImportKind in interface IImportNode

Returns:

an IImportNode

getImportNameNode

public IExpressionNode getImportNameNode()

Description copied from interface: IImportNode

Returns the expression underlying this import node

Specified by:

getImportNameNode in interface IImportNode

Returns:

an IExpressionNode for this import

getImportName

public String getImportName()

Description copied from interface: IImportNode

Get the name of the target definition we are importing

Specified by:

getImportName in interface IImportNode

Returns:

name of package to import

getImportTarget

public IImportTarget getImportTarget()

Description copied from interface: IImportNode

Creates an import target for the given import

Specified by:

getImportTarget in interface IImportNode

Returns:

an IImportTarget

isWildcardImport

public boolean isWildcardImport()

Description copied from interface: IImportNode

Returns whether an import statement is a wildcard import or not

Specified by:

isWildcardImport in interface IImportNode

Returns:

true if a wildcard import

resolveImport

public IDefinition resolveImport(ICompilerProject project)

Description copied from interface: IImportNode

Returns the definition being imported, or null if this is a wildcard import or if the import name cannot be resolved.

Specified by:

resolveImport in interface IImportNode

Parameters:

project - An ICompilerProject within which references are resolved.

Returns:

An IDefinition or null.

setImportKind

public void setImportKind(IImportNode.ImportKind importKind)

Sets the type of import we have encountered. Used during parsing, defaults to AS_SCOPED_IMPORT

Parameters:

importKind - The type of import.

setImportTarget

public void setImportTarget(ExpressionNodeBase targetImportNode)

Sets the import target. Used during parsing.

Parameters:

targetImportNode - The node representing the import target.
