NamespaceBinding
public NamespaceBinding(java.lang.String prefix, java.lang.String uri)
Create a binding of a prefix to a URI- Parameters:
prefix
- the prefix: either an NCName, or a zero-length string to bind the default namespace. Must not be null.uri
- the namespace URI: either a URI, or a zero-length string to unbind the prefix. Must not be null.

Method Detail

makeNamespaceBinding
public static NamespaceBinding makeNamespaceBinding(java.lang.CharSequence prefix, java.lang.CharSequence uri)
Create a binding of a prefix to a URI. Static factory method for the convenience of compiled bytecode; reuses standard NamespaceBinding objects where possible- Parameters:
prefix
- the prefix: either an NCName, or a zero-length string to bind the default namespace. Must not be null.uri
- the namespace URI: either a URI, or a zero-length string to unbind the prefix. Must not be null.- Returns:
- the namespace binding object
-
getPrefix
public java.lang.String getPrefix()
Get the prefix part of the binding- Returns:
- the prefix. Never null. The zero-length string indicates a binding for the default namespace.
-
getURI
public java.lang.String getURI()
Get the URI part of the binding- Returns:
- the URI. Never null. The zero-length string indicates an unbinding of the prefix. For the default namespace (prefix="") this indicates that the prefix refers to names in no namespace; for other prefixes, it indicates that the prefix is not bound to any namespace and therefore cannot be used.
-
isXmlNamespace
public boolean isXmlNamespace()
Ask whether this is a binding for the XML namespace- Returns:
- true if this is the binding of the prefix "xml" to the standard XML namespace.
-
isDefaultUndeclaration
public boolean isDefaultUndeclaration()
Ask whether this is an undeclaration of the default prefix, that is, a namespace binding corresponding toxmlns=""
- Returns:
- true if this corresponding to
xmlns=""
-
equals
public boolean equals(java.lang.Object obj)
Test if this namespace binding is the same as another- Overrides:
equals
in classjava.lang.Object
- Parameters:
obj
- the comparand- Returns:
- true if the comparand is a Namespace binding of the same prefix to the same URI
-
hashCode
public int hashCode()
- Overrides:
