Method Detail

matcher

public static ImageMatcher matcher(java.lang.CharSequence content)

Creates a new image matcher from given content.

Parameters:

content - The content

Returns:

The appropriate matcher

setPrefixService

public static void setPrefixService(com.openexchange.dispatcher.DispatcherPrefixService prefixService)

Parameters:

prefixService -

group

public java.lang.String group()

Returns the matching image tag.

Returns:

The matching image tag.

Throws:

java.lang.IllegalStateException - If no match has yet been attempted, or if the previous match operation failed

group

public java.lang.String group(int group)

Returns the input subsequence captured by the given group during the previous match operation.

Parameters:

group - The index of a capturing group in this matcher's pattern

Returns:

The (possibly empty) subsequence captured by the group during the previous match, or null if the group failed to match part of the input

Throws:

java.lang.IllegalStateException - If no match has yet been attempted, or if the previous match operation failed

java.lang.IndexOutOfBoundsException - If there is no capturing group in the pattern with the given index

groupCount

public int groupCount()

Returns the number of capturing groups in this matcher's pattern.

Group zero denotes the entire pattern by convention. It is not included in this count.

Any non-negative integer smaller than or equal to the value returned by this method is guaranteed to be a valid group index for this matcher.

Returns:

The number of capturing groups in this matcher's pattern

matches

public boolean matches()

Attempts to match the entire region against the pattern.

If the match succeeds then more information can be obtained via the start, end, and group methods.

Returns:

true if, and only if, the entire region sequence matches this matcher's pattern

find

public boolean find()

Attempts to find the next subsequence of the input sequence that matches the pattern.

This method starts at the beginning of this matcher's region, or, if a previous invocation of the method was successful and the matcher has not since been reset, at the first character not matched by the previous match.

If the match succeeds then more information can be obtained via the start, end, and group methods.

Returns:

true if, and only if, a subsequence of the input sequence matches this matcher's pattern

getManagedFileId

public java.lang.String getManagedFileId()

Gets the managed file identifier.

Returns:

The identifier

getImageId

public java.lang.String getImageId()

Gets the image identifier

Returns:

The identifier

start

public int start()

Gets the start index of the previous match.

Returns:

The start index

end

public int end()

Gets the end index of the previous match.

Returns:

The end index

appendReplacement

public java.util.regex.Matcher appendReplacement(java.lang.StringBuffer sb,
                                        java.lang.String replacement)

Implements a non-terminal append-and-replace step.

appendLiteralReplacement

public java.util.regex.Matcher appendLiteralReplacement(java.lang.StringBuffer sb,
                                               java.lang.String replacement)

Implements a non-terminal append-and-replace step.

appendTail

public java.lang.StringBuffer appendTail(java.lang.StringBuffer sb)

Implements a non-terminal append-and-replace step.
