Field Summary

Fields
Modifier and Type	Field and Description
`static int`	`ALL`
`static int`	`COLLAPSE`
`static int`	`IGNORABLE`
`static int`	`NONE` The values NONE, IGNORABLE, and ALL identify which kinds of whitespace text node should be stripped when building a source tree
`static int`	`PRESERVE` The values PRESERVE, REPLACE, and COLLAPSE represent the three options for whitespace normalization.
`static int`	`REPLACE`
`static int`	`UNSPECIFIED`

  - PRESERVE
```
public static final int PRESERVE
```
    The values PRESERVE, REPLACE, and COLLAPSE represent the three options for whitespace normalization. They are deliberately chosen in ascending strength order; given a number of whitespace facets, only the strongest needs to be carried out.

- Method Detail
  - isWhitespace
```
public static boolean isWhitespace(int ch)
```
    Test whether a character is whitespace
  - applyWhitespaceNormalization
```
public static CharSequence applyWhitespaceNormalization(int action,
                                                        CharSequence value)
```
    Apply schema-defined whitespace normalization to a string
    
    Parameters:
    
    action - the action to be applied: one of PRESERVE, REPLACE, or COLLAPSE
    
    value - the value to be normalized
    
    Returns:
    
    the value after normalization
  - removeAllWhitespace
```
public static CharSequence removeAllWhitespace(CharSequence value)
```
    Remove all whitespace characters from a string
  - removeLeadingWhitespace
```
public static CharSequence removeLeadingWhitespace(CharSequence value)
```
    Remove leading whitespace characters from a string
  - containsWhitespace
```
public static boolean containsWhitespace(CharSequence value)
```
    Determine if a string contains any whitespace
  - isWhite
```
public static final boolean isWhite(CharSequence content)
```
    Determine if a string is all-whitespace
    
    Parameters:
    
    content - the string to be tested
    
    Returns:
    
    true if the supplied string contains no non-whitespace characters
  - normalizeWhitespace
```
public static CharSequence normalizeWhitespace(CharSequence in)
```
    Normalize whitespace as defined in XML Schema
  - collapseWhitespace
```
public static CharSequence collapseWhitespace(CharSequence in)
```
    Collapse whitespace as defined in XML Schema
  - trimWhitespace
```
public static CharSequence trimWhitespace(CharSequence in)
```
    Remove leading and trailing whitespace. This has the same effect as collapseWhitespace, but is cheaper, for use by data types that do not allow internal whitespace.
    
    Parameters:
    
    in - the input string whose whitespace is to be removed
    
    Returns:
    
    the result of removing excess whitespace
