Class Overview
Base interface for all elements of a Java Abstract Syntax Tree.
Each AST element implements this interface or one of the sub-interfaces, such as:
- the
INonStatementinterface. Examples:method,constant,static field, etc. - the
IStatementinterface. Examples: Assignment assignment, Continue continue, WhileStm while, etc.

Public Methods
public abstract Object addTag (String key, Object value)
Add a tag.
public abstract void collectAllPhysicalOffsets (Collection<Integer> physicalOffsets)
Collect physical offsets for this element and all its constituents. The first element
added is for 'this' one, then getSubElements()'s.
Parameters
| physicalOffsets | output collection |
|---|
public abstract Object getData (Object key)
Retrieve a piece of data attached to this AST element.
public abstract JavaElementType getElementType ()
This convenience method returns the type of Java AST element held by this object.
public abstract int getPhysicalOffset ()
Return the lowest-level offset that map to this AST element.
Returns
- a physical method offset, -1 if none is available
public abstract List<? extends IJavaElement> getSubElements ()
Get the list of AST elements that constitute this AST element. Typically, for simple statements, it may be expression. For complex expressions, it may be simpler expressions. For compound statements, it may more statements and expressions.
Note that type and annotation elements are not
returned by this method.
Returns
- the list of constituting elements, may be empty but never null
public abstract Map<String, Object> getTags ()
Get a read-only collection of the current tag map.
public abstract boolean hasPhysicalOffset ()
public abstract Object removeTag (String key)
Remove a tag.
public abstract boolean replaceSubElement (IJavaElement oldElement, IJavaElement newElement)
Replace one element by another one. Only the references are compared, no equals/deep compare. At most one element is replaced.
Note that type and annotation elements cannot be
replaced using this method.
Parameters
| oldElement | the element to be replaced |
|---|---|
| newElement | the new element |
public abstract void setData (String key, Object value)
Attach a piece of data to this AST element.
