compareToback to summary
public int compareTo(CatchHandlerList other)

Implements java.lang.Comparable.compareTo.

Doc from java.lang.Comparable.compareTo.

Compares this object with the specified object for order. Returns a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object.

The implementor must ensure signum(x.compareTo(y)) == -signum(y.compareTo(x)) for all x and y. (This implies that x.compareTo(y) must throw an exception if and only if y.compareTo(x) throws an exception.)

The implementor must also ensure that the relation is transitive: (x.compareTo(y) > 0 && y.compareTo(z) > 0) implies x.compareTo(z) > 0.

Finally, the implementor must ensure that x.compareTo(y)==0 implies that signum(x.compareTo(z)) == signum(y.compareTo(z)), for all z.

Parameters
other:CatchHandlerList

the object to be compared.

Returns:int

a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object.

getback to summary
public CatchHandlerList.Entry get(int n)

Gets the element at the given index. It is an error to call this with the index for an element which was never set; if you do that, this will throw NullPointerException.

Parameters
n:int

>= 0, < size(); which index

Returns:CatchHandlerList.Entry

non-null; element at that index

setback to summary
public void set(int n, CstType exceptionType, int handler)

Sets the entry at the given index.

Parameters
n:int

>= 0, < size(); which index

exceptionType:CstType

non-null; type of exception handled

handler:int

>= 0; exception handler address

setback to summary
public void set(int n, CatchHandlerList.Entry entry)

Sets the entry at the given index.

Parameters
n:int

>= 0, < size(); which index

entry:CatchHandlerList.Entry

non-null; the entry to set at n

public String toHuman()

Overrides org.droidparts.dexmaker.dx.util.FixedSizeList.toHuman.

Implements org.droidparts.dexmaker.dx.util.ToHuman.toHuman.

Doc from org.droidparts.dexmaker.dx.util.FixedSizeList.toHuman.

Return the "human" string form of this instance. This is generally less "debuggy" than toString(). This method will only work if every element of the list implements ToHuman.

Returns:String

Doc from org.droidparts.dexmaker.dx.util.ToHuman.toHuman.

non-null; the human string form

toHumanback to summary
public String toHuman(String prefix, String header)

Get the human form of this instance, prefixed on each line with the string.

Parameters
prefix:String

non-null; the prefix for every line

header:String

non-null; the header for the first line (after the first prefix)

Returns:String

non-null; the human form

Method Detail

compareToback to summary
public int compareTo(CatchHandlerList.Entry other)

Implements java.lang.Comparable.compareTo.

Doc from java.lang.Comparable.compareTo.

Compares this object with the specified object for order. Returns a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object.

The implementor must ensure signum(x.compareTo(y)) == -signum(y.compareTo(x)) for all x and y. (This implies that x.compareTo(y) must throw an exception if and only if y.compareTo(x) throws an exception.)

The implementor must also ensure that the relation is transitive: (x.compareTo(y) > 0 && y.compareTo(z) > 0) implies x.compareTo(z) > 0.

Finally, the implementor must ensure that x.compareTo(y)==0 implies that signum(x.compareTo(z)) == signum(y.compareTo(z)), for all z.

Parameters
other:CatchHandlerList.Entry

the object to be compared.

Returns:int

a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object.

equalsback to summary
public boolean equals(Object other)

Overrides java.lang.Object.equals.

Doc from java.lang.Object.equals.

Indicates whether some other object is "equal to" this one.

The equals method implements an equivalence relation on non-null object references:

  • It is reflexive: for any non-null reference value x, x.equals(x) should return true.
  • It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
  • It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
  • It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
  • For any non-null reference value x, x.equals(null) should return false.

An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.

Parameters
other:Object

the reference object with which to compare.

Returns:boolean

true if this object is the same as the obj argument; false otherwise.

getExceptionTypeback to summary
public CstType getExceptionType()

Gets the exception type handled.

Returns:CstType

non-null; the exception type

getHandlerback to summary
public int getHandler()

Gets the handler address.

Returns:int

>= 0; the handler address

hashCodeback to summary
public int hashCode()

Overrides java.lang.Object.hashCode.

Doc from java.lang.Object.hashCode.

Returns a hash code value for this object. This method is supported for the benefit of hash tables such as those provided by java.util.HashMap.

The general contract of hashCode is:

  • Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
  • If two objects are equal according to the equals method, then calling the hashCode method on each of the two objects must produce the same integer result.
  • It is not required that if two objects are unequal according to the equals method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.
Returns:int

a hash code value for this object
