Class NamespaceDeclarationsImpl

  • All Implemented Interfaces:
    NamespaceDeclarations
    public class NamespaceDeclarationsImpl
extends java.lang.Object
implements NamespaceDeclarations
    An implementation of the NamespaceDeclarations interface, based on encapsulating an array of namespace codes.

    • Method Summary

      All Methods Instance Methods Concrete Methods 
      Modifier and Type Method Description
      int getNamespaceCode​(int index)
      Get the n'th declaration in the list in the form of a namespace code.
      int[] getNamespaceCodes​(int[] buffer)
      Get all the namespace codes, as an array.
      int getNumberOfNamespaces()
      Get the number of declarations (and undeclarations) in this list.
      java.lang.String getPrefix​(int index)
      Get the prefix of the n'th declaration (or undeclaration) in the list, counting from zero.
      java.lang.String getURI​(int index)
      Get the namespace URI of the n'th declaration (or undeclaration) in the list, counting from zero.
      void setNamePool​(NamePool pool)
      Set the name pool
      void setNamespaceCodes​(int[] codes)
      Set the namespace codes.

      • NamespaceDeclarationsImpl

        public NamespaceDeclarationsImpl()

      • NamespaceDeclarationsImpl

        public NamespaceDeclarationsImpl​(NamePool pool,
                                 int[] codes)
        Construct a set of namespace declarations
        Parameters:
        pool - the name pool
        codes - an integer array holding the namespace codes. These codes are allocated by the name pool, and can be used to look up a prefix and uri in the name pool. If the array contains the integer -1, this acts as a terminator for the list. This is the format returned by the method NodeInfo.getDeclaredNamespaces(int[]). A value of null is equivalent to supplying an empty array.

    • Method Detail

      • setNamePool

        public void setNamePool​(NamePool pool)
        Set the name pool

      • setNamespaceCodes

        public void setNamespaceCodes​(int[] codes)
        Set the namespace codes.
        Parameters:
        codes - an integer array holding the namespace codes. These codes are allocated by the name pool, and can be used to look up a prefix and uri in the name pool. If the array contains the integer -1, this acts as a terminator for the list. This is the format returned by the method NodeInfo.getDeclaredNamespaces(int[]). A value of null is equivalent to supplying an empty array.

      • getNamespaceCodes

        public int[] getNamespaceCodes​(int[] buffer)
        Get all the namespace codes, as an array.
        Specified by:
        getNamespaceCodes in interface NamespaceDeclarations
        Parameters:
        buffer - a sacrificial array that the method is free to use to contain the result. May be null.
        Returns:
        an integer array containing namespace codes. The array may be filled completely with namespace codes, or it may be incompletely filled, in which case a -1 integer acts as a terminator.

      • getPrefix

        public java.lang.String getPrefix​(int index)
        Get the prefix of the n'th declaration (or undeclaration) in the list, counting from zero.
        Specified by:
        getPrefix in interface NamespaceDeclarations
        Parameters:
        index - the index identifying which declaration is required.
        Returns:
        the namespace prefix. For a declaration or undeclaration of the default namespace, this is the zero-length string.
        Throws:
        java.lang.IndexOutOfBoundsException - if the index is out of range.

      • getURI

        public java.lang.String getURI​(int index)
        Get the namespace URI of the n'th declaration (or undeclaration) in the list, counting from zero.
        Specified by:
        getURI in interface NamespaceDeclarations
        Parameters:
        index - the index identifying which declaration is required.
        Returns:
        the namespace URI. For a namespace undeclaration, this is the zero-length string.
        Throws:
        java.lang.IndexOutOfBoundsException - if the index is out of range.

      • getNamespaceCode

        public int getNamespaceCode​(int index)
        Get the n'th declaration in the list in the form of a namespace code. Namespace codes can be translated into a prefix and URI by means of methods in the NamePool
        Specified by:
        getNamespaceCode in interface NamespaceDeclarations
        Parameters:
        index - the index identifying which declaration is required.
        Returns:
        the namespace code. This is an integer whose upper half indicates the prefix (0 represents the default namespace), and whose lower half indicates the URI (0 represents an undeclaration).
        Throws:
        java.lang.IndexOutOfBoundsException - if the index is out of range.
