Ensure that the given index is >=0 and lower than the given length.

Parameters

index - an int

Returns:

void (returns nothing)

Parameters

sb - non-null string buffer to append to.
ch - character to be debugged.

Returns:

debugChar( java.lang.StringBuilder sb, char ch ) → void
debugChar( char ch ) → String

debugText

debugText( java.lang.StringBuffer sb, java.lang.CharSequence text ) → void

Append the text description to the given string buffer translating the special characters (and '\') into escape sequences.

Parameters

sb - non-null string buffer to append to.
text - non-null text to be debugged.

debugText( java.lang.StringBuilder sb, java.lang.CharSequence text ) → void
debugText( java.lang.CharSequence text ) → String

endsWith

endsWith( java.lang.CharSequence text, java.lang.CharSequence suffix ) → boolean

Parameters

text - a CharSequence
suffix - a CharSequence

Returns:

boolean

equals

equals( java.lang.CharSequence text, Object o ) → boolean

Compare character sequence to another object. The match is successful if the second object is a character sequence as well and both character sequences contain the same characters (or if both objects are null).

Parameters

text - character sequence being compared to the given object. It may be null.
o - object to be compared to the character sequence. It may be null.

Returns:

true if both parameters are null or both are non-null and they contain the same text.

textEquals

textEquals( java.lang.CharSequence text1, java.lang.CharSequence text2 ) → boolean

Test whether whether the given character sequences represent the same text.
The match is successful if the contained characters of the two character sequences are the same.

Parameters

text1 - first character sequence being compared. It must not be null.
