Constructor Detail

DelimiterSet

public DelimiterSet()

Create a delimiter set with the default delimiters (comma for fields, newline for records).

DelimiterSet

public DelimiterSet(char field,
                    char record,
                    char enclose,
                    char escape,
                    boolean isEncloseRequired)

Create a delimiter set with the specified delimiters.

Parameters:

field - the fields-terminated-by delimiter

record - the lines-terminated-by delimiter

enclose - the enclosed-by character

escape - the escaped-by character

isEncloseRequired - If true, enclosed-by is applied to all fields. If false, only applied to fields that embed delimiters.

Method Detail

copy

public DelimiterSet copy()

Identical to clone() but does not throw spurious exceptions.

Returns:

a new copy of this same set of delimiters.

setFieldsTerminatedBy

public void setFieldsTerminatedBy(char f)

Sets the fields-terminated-by character.

getFieldsTerminatedBy

public char getFieldsTerminatedBy()

Returns:

the fields-terminated-by character.

setLinesTerminatedBy

public void setLinesTerminatedBy(char r)

Sets the end-of-record lines-terminated-by character.

getLinesTerminatedBy

public char getLinesTerminatedBy()

Returns:

the end-of-record (lines-terminated-by) character.

setEnclosedBy

public void setEnclosedBy(char e)

Sets the enclosed-by character.

Parameters:

e - the enclosed-by character, or '\000' for no enclosing character.

getEnclosedBy

public char getEnclosedBy()

Returns:

the enclosed-by character, or '\000' for none.

setEscapedBy

public void setEscapedBy(char e)

Sets the escaped-by character.

Parameters:

e - the escaped-by character, or '\000' for no escape character.

getEscapedBy

public char getEscapedBy()

Returns:

the escaped-by character, or '\000' for none.

setEncloseRequired

public void setEncloseRequired(boolean required)

Set whether the enclosed-by character must be applied to all fields, or only fields with embedded delimiters.

isEncloseRequired

public boolean isEncloseRequired()

Returns:

true if the enclosed-by character must be applied to all fields, or false if it's only used for fields with embedded delimiters.

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

formatConstructor

public java.lang.String formatConstructor()

Format this set of delimiters as a call to the constructor for this object, that would generate identical delimiters.

Returns:

a String that can be embedded in generated code that provides this set of delimiters.

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

equals

public boolean equals(java.lang.Object other)

Overrides:

equals in class java.lang.Object

clone

public java.lang.Object clone()
                       throws java.lang.CloneNotSupportedException

Overrides:

clone in class java.lang.Object

Throws:

java.lang.CloneNotSupportedException
