Constructor Detail

Tag

private Tag(int line,
            int column,
            String text,
            SuppressionCommentFilter.TagType tagType,
            SuppressionCommentFilter filter)

Constructs a tag.

Parameters:

line - the line number.

column - the column number.

text - the text of the suppression.

tagType - ON if the tag turns checkstyle reporting.

filter - the SuppressionCommentFilter with the context

Throws:

IllegalArgumentException - if unable to parse expanded text.

Method Detail

getLine

public int getLine()

Returns line number of the tag in the source file.

Returns:

the line number of the tag in the source file.

getColumn

public int getColumn()

Determines the column number of the tag in the source file. Will be 0 for all lines of multiline comment, except the first line.

Returns:

the column number of the tag in the source file.

getTagType

public SuppressionCommentFilter.TagType getTagType()

Determines whether the suppression turns checkstyle reporting on or off.

Returns:

ON if the suppression turns reporting on.

compareTo

public int compareTo(SuppressionCommentFilter.Tag object)

Compares the position of this tag in the file with the position of another tag.

Specified by:

compareTo in interface Comparable<SuppressionCommentFilter.Tag>

Parameters:

object - the tag to compare with this one.

Returns:

a negative number if this tag is before the other tag, 0 if they are at the same position, and a positive number if this tag is after the other tag.

equals

public boolean equals(Object other)

Indicates whether some other object is "equal to" this one. Suppression on enumeration is needed so code stays consistent.

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

isMatch

Determines whether the source of an audit event matches the text of this tag.

Parameters:

event - the TreeWalkerAuditEvent to check.

Returns:

true if the source of event matches the text of this tag.

isCheckMatch

private boolean isCheckMatch(TreeWalkerAuditEvent event)

Checks whether TreeWalkerAuditEvent source name matches the check format.

Parameters:

event - TreeWalkerAuditEvent instance.

Returns:

true if the TreeWalkerAuditEvent source name matches the check format.

isIdMatch

private boolean isIdMatch(TreeWalkerAuditEvent event)

Checks whether the TreeWalkerAuditEvent module ID matches the ID format.

Parameters:

event - TreeWalkerAuditEvent instance.

Returns:

true if the TreeWalkerAuditEvent module ID matches the ID format.

isMessageMatch

private boolean isMessageMatch(TreeWalkerAuditEvent event)

Checks whether the TreeWalkerAuditEvent message matches the message format.

Parameters:

event - TreeWalkerAuditEvent instance.

Returns:

true if the TreeWalkerAuditEvent message matches the message format.

toString

public String toString()
