Method Summary

static String	docCommentToHtml(String dc) Converts a Java documentation comment to HTML.
static CompilationUnit	getCompilationUnitFromDisk(File loc, ClassFile cf) Used by MemberCompletion.Data implementations to get an AST from a source file in a directory or zip/jar file.
static String	getUnqualified(String clazz) Returns the "unqualified" version of a (possibly) fully-qualified class name.
static boolean	isFullyQualified(String str) Returns whether the specified string is "fully qualified," that is, whether it contains a '.' character.
static String	replaceChar(String str, char oldCh, char newCh) Does a fast replacement of all instances of one char with another.
static String[]	splitOnChar(String str, int ch) A faster way to split on a single char than String#split(), since we'll be doing this in a tight loop possibly thousands of times (rt.jar).

Method Detail

docCommentToHtml

public static final String docCommentToHtml(String dc)

Converts a Java documentation comment to HTML.

Parameters:

dc - The documentation comment.

Returns:

An HTML version of the comment.

getCompilationUnitFromDisk

public static CompilationUnit getCompilationUnitFromDisk(File loc,
                                                         ClassFile cf)

Used by MemberCompletion.Data implementations to get an AST from a source file in a directory or zip/jar file.

Parameters:

loc - A directory or zip/jar file.

cf - The ClassFile representing the source grab from the location.

Returns:

The compilation unit, or null if it is not found or an IO error occurs.

getUnqualified

public static final String getUnqualified(String clazz)

Returns the "unqualified" version of a (possibly) fully-qualified class name.

Parameters:

clazz - The class name.

Returns:

The unqualified version of the name.

isFullyQualified

public static final boolean isFullyQualified(String str)

Returns whether the specified string is "fully qualified," that is, whether it contains a '.' character.

Parameters:

str - The string to check.

Returns:

Whether the string is fully qualified.

replaceChar

public static final String replaceChar(String str,
                                       char oldCh,
                                       char newCh)

Does a fast replacement of all instances of one char with another.

Parameters:

str - The string to do the replacements in.

oldCh - The character to look for.

newCh - The character to replace with.

Returns:

The string, possibly with the char replaced.

splitOnChar

public static final String[] splitOnChar(String str,
                                         int ch)

A faster way to split on a single char than String#split(), since we'll be doing this in a tight loop possibly thousands of times (rt.jar). This is also fundamentally different than String.split(String)), in the case where str ends with ch - this method will return an empty item at the end of the returned array, while String#split() will not.

Parameters:

str - The string to split.

ch - The char to split on.

Returns:

The string, split on the character (e.g. '/' or '.').
