Enum Constant Summary

Enum Constants

Enum Constant and Description
ALONE Represents the policy that the brace must be alone on the line.
ALONE_OR_SINGLELINE Represents the policy that the brace must be alone on the line, yet allows single-line format of block.
SAME Represents the policy that the brace should be on the same line as the the next part of a multi-block statement (one that directly contains multiple blocks: if/else-if/else or try/catch/finally).

Enum Constant Detail

ALONE_OR_SINGLELINE

public static final RightCurlyOption ALONE_OR_SINGLELINE

Represents the policy that the brace must be alone on the line, yet allows single-line format of block. For example:

 // Brace is alone on the line
 try {
     ...
 }
 finally {
     ...
 }

 // Single-line format of block
 public long getId() { return id; }
 

ALONE

public static final RightCurlyOption ALONE

Represents the policy that the brace must be alone on the line. For example:

 try {
     ...
 }
 finally {
     ...
 }
 

SAME

public static final RightCurlyOption SAME

Represents the policy that the brace should be on the same line as the the next part of a multi-block statement (one that directly contains multiple blocks: if/else-if/else or try/catch/finally). It also allows single-line format of multi-block statements.

Examples:

 // try-catch-finally blocks
 try {
     ...
 } catch (Exception ex) { // this is OK
     ...
 } finally { // this is OK
     ...
 }

 try {
     ...
 } // this is NOT OK, not on the same line as the next part of a multi-block statement
 catch (Exception ex) {
     ...
 } // this is NOT OK, not on the same line as the next part of a multi-block statement
 finally {
     ...
 }

 // if-else blocks
 if (a > 0) {
     ...
 } else { // this is OK
     ...
 }

 if (a > 0) {
     ...
 } // this is NOT OK, not on the same line as the next part of a multi-block statement
 else {
     ...
 }

 if (a > 0) {
     ...
 } int i = 5; // this is NOT OK, next part of a multi-block statement is absent

 // Single line blocks will rise violations, because right curly
 // brace is not on the same line as the next part of a multi-block
 // statement, it just ends the line.
 public long getId() {return id;} // this is NOT OK

 Thread t = new Thread(new Runnable() {
  @Override
  public void run() {
                ...
  } // this is NOT OK, not on the same line as the next part of a multi-block statement
 }); // this is OK, allowed for better code readability

 if (a > 0) { ... } // OK, single-line multi-block statement
 if (a > 0) { ... } else { ... } // OK, single-line multi-block statement
 if (a > 0) {
     ...
 } else { ... } // OK, single-line multi-block statement
 

Method Detail

values

public static RightCurlyOption[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (RightCurlyOption c : RightCurlyOption.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static RightCurlyOption valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
