Method Detail

isNCNameChar

@Deprecated
public static boolean isNCNameChar(char ch)

Deprecated. Use XMLUtils.isNCNameChar(int)

isNCNameStartChar

@Deprecated
public static boolean isNCNameStartChar(char ch)

Deprecated. Use XMLUtils.isNCNameStartChar(int)

split

@Deprecated
public String[] split(String s,
                        String[] result)

Deprecated. Use XMLUtils.getNCNamePrefix(CharSequence)

Splits a string into a namespace and local name.

Parameters:

s - The string to be split.

result - May be null. If not null the method will fill the array with the result and return the passed in array. This allows a String array to be reused. If this parameter is null then a new String array will be created to hold the result. The size of the array must be 2

Returns:

The result of the split. The first element corresponds to the namespace and the second element corresponds to the local name. If the string could not be split into a namespace and local name then the first element will be an empty string and the second element will an empty string

split

@Deprecated
public String[] split(String s)

Deprecated. Use XMLUtils.getNCNamePrefix(CharSequence)

getPrefix

public String getPrefix(String namespace)

Gets a prefix for the given namespace. If a mapping has not been specified then a prefix will be computed and stored for the specified namespace.

Parameters:

namespace - The namespace whose prefix is to be retrieved.

Returns:

The prefix for the specified namespace.

getNamespace2PrefixMap

public Map<String,String> getNamespace2PrefixMap()

generatePrefix

public String generatePrefix(String namespace)

Generates a candidate prefix for the specified namespace.

Parameters:

namespace - The namespace that a prefix should be generated for. The implementation attempts to generate a prefix based on the namespace. If it cannot do this, a prefix of the form pn is generated, where n is an integer.

Returns:

The generated prefix. Note that this method will not store the namespace -> prefix mapping.

setPrefix

public void setPrefix(String namespace,
             String prefix)

Sets the prefix for the specified namespace. This will override any computed prefix and take precedence over any computed prefix.

Parameters:

namespace - The namespace whose prefix is to be set.

prefix - The prefix for the namespace
