Field Summary

Constructor Summary

SyntaxScheme(boolean useDefaults)
Creates a color scheme that either has all color values set to a default value or set to null.

Method Summary

java.lang.Object	clone() Returns a deep copy of this color scheme.
boolean	equals(java.lang.Object otherScheme) Tests whether this color scheme is the same as another color scheme.
int	hashCode() This is implemented to be consistent with equals(Object).
static SyntaxScheme	loadFromString(java.lang.String string) Loads a syntax highlighting color scheme from a string created from toCommaSeparatedString.
void	restoreDefaults() Restores all colors and fonts to their default values.
void	setStyle(int type, Style style) Sets a style to use when rendering a token type.
java.lang.String	toCommaSeparatedString() Returns this syntax highlighting scheme as a comma-separated list of values as follows: If a color is non-null, it is added as a 24-bit integer of the form ((r<<16) | (g<<8) | (b)); if it is null, it is added as "-,".

Constructor Detail

SyntaxScheme

public SyntaxScheme(boolean useDefaults)

Creates a color scheme that either has all color values set to a default value or set to null.

Parameters:

useDefaults - If true, all color values will be set to default colors; if false, all colors will be initially null.

Method Detail

clone

public java.lang.Object clone()

Returns a deep copy of this color scheme.

Overrides:

clone in class java.lang.Object

Returns:

The copy.

equals

public boolean equals(java.lang.Object otherScheme)

Tests whether this color scheme is the same as another color scheme.

Overrides:

equals in class java.lang.Object

Parameters:

otherScheme - The color scheme to compare to.

Returns:

true if this color scheme and otherScheme are the same scheme; false otherwise.

hashCode

public int hashCode()

This is implemented to be consistent with equals(Object). This is a requirement to keep FindBugs happy.

Overrides:

hashCode in class java.lang.Object

Returns:

The hash code for this object.

loadFromString

public static SyntaxScheme loadFromString(java.lang.String string)

Loads a syntax highlighting color scheme from a string created from toCommaSeparatedString. This method is useful for saving and restoring color schemes.

Parameters:

string - A string generated from toCommaSeparatedString().

Returns:

A color scheme.

restoreDefaults

public void restoreDefaults()

Restores all colors and fonts to their default values.

setStyle

public void setStyle(int type,
                     Style style)

Sets a style to use when rendering a token type.

Parameters:

type - The token type.

style - The style for the token type.

toCommaSeparatedString

public java.lang.String toCommaSeparatedString()

Returns this syntax highlighting scheme as a comma-separated list of values as follows:

• If a color is non-null, it is added as a 24-bit integer of the form ((r<<16) | (g<<8) | (b)); if it is null, it is added as "-,".
• The font and style (bold/italic) is added as an integer like so: "family, style, size".
• The entire syntax highlighting scheme is thus one long string of color schemes of the format "i,[fg],[bg],uline,[style], where:
  • i is the index of the syntax scheme.
  • fg and bg are the foreground and background colors for the scheme, and may be null (represented by -).
  • uline is whether or not the font should be underlined, and is either t or f.
  • style is the family,style,size triplet described above.

Returns:

A string representing the rgb values of the colors.
