Class StringFilter

java.lang.Object
  extended by org.htmlparser.filters.StringFilter
All Implemented Interfaces:
Serializable, Cloneable, NodeFilter

public class StringFilter
extends Object
implements NodeFilter

This class accepts all string nodes containing the given string. This is a fairly simplistic filter, so for more sophisticated string matching, for example newline and whitespace handling, use a RegexFilter instead.

Field Detail

mPattern

protected String mPattern
The string to search for.


mUpperPattern

protected String mUpperPattern
The string to really search for (converted to uppercase if necessary).


mCaseSensitive

protected boolean mCaseSensitive
Case sensitive toggle. If true strings are compared with case sensitivity.


mLocale

protected Locale mLocale

Constructor Detail

StringFilter

public StringFilter()
Creates a new instance of StringFilter that accepts all string nodes.


StringFilter

public StringFilter(String pattern)
Creates a StringFilter that accepts text nodes containing a string. The comparison is case insensitive, with conversions done using the default Locale.

Parameters:
pattern - The pattern to search for.

StringFilter

public StringFilter(String pattern,
                    boolean sensitive)
Creates a StringFilter that accepts text nodes containing a string.

Parameters:
pattern - The pattern to search for.
sensitive - If true, comparisons are performed respecting case, with conversions done using the default Locale.

StringFilter

public StringFilter(String pattern,
                    boolean sensitive,
                    Locale locale)
Creates a StringFilter that accepts text nodes containing a string.

Parameters:
pattern - The pattern to search for.
sensitive - If true, comparisons are performed respecting case.
locale - The locale to use when converting to uppercase. If null, the default Locale is used.
Method Detail

setUpperPattern

protected void setUpperPattern()
Set the real (upper case) comparison string.


getCaseSensitive

public boolean getCaseSensitive()
Get the case sensitivity.

Returns:
Returns the case sensitivity.

setCaseSensitive

public void setCaseSensitive(boolean sensitive)
Set case sensitivity on or off.

Parameters:
sensitive - If false searches for the string are case insensitive.

getLocale

public Locale getLocale()
Get the locale for uppercase conversion.

Returns:
Returns the locale.

setLocale

public void setLocale(Locale locale)
Set the locale for uppercase conversion.

Parameters:
locale - The locale to set.

getPattern

public String getPattern()
Get the search pattern.

Returns:
Returns the pattern.

setPattern

public void setPattern(String pattern)
Set the search pattern.

Parameters:
pattern - The pattern to set.

accept

public boolean accept(Node node)
Accept string nodes that contain the string.
