IDebugExpression Interface
- public interface IDebugExpression
This is the interface for an expression. It is used by the watch window
and the locals window for displaying values to the user. All of the values
except isStale()
are immutable. After evaluating an expression,
a new IDebugExpression will be created to hold the values, but after the value
becomes stale the expression's stale state will be toggled to true.
public static final int |
-
NOT_ARRAY
- Used as the arrayLength property for values that do not represent arrays
|
public int |
-
getArrayLength ()
- Gets the length of this expression's value if it's an array, or indicates it's not an array
|
public String |
-
getDeclaredType ()
- If known, the declared type of the expression.
|
public String |
-
getExpression ()
- Gets the expression of this IDebugExpression, corresponding to its name in the current scope,
such as "localVariable.someField"
|
public String [] |
-
getInterfaces ()
- Gets the list of interfaces implemented by this object.
|
public String |
-
getValue ()
- Gets the Value of this IDebugExpression
|
public String |
-
getValueType ()
- Gets the type of the Value of this IDebugExpression, such as "int" or "java.lang.StringBuffer"
|
public boolean |
-
isComplex ()
- IDebugExpressions are complex if they have children that are visible in the debugger
|
public boolean |
-
isEditable ()
- Gets whether the expression is editable or not.
|
public boolean |
-
isError ()
- Returns whether this expression caused an error getting evaluated or not.
|
public boolean |
-
isStale ()
- Gets whether the expression is stale or not.
|
public boolean |
-
isStatic ()
- Gets whether the expression is for a static member or not.
|
NOT_ARRAY
public static final int NOT_ARRAY
- Used as the arrayLength property for values that do not represent arrays
getArrayLength() Method
public int getArrayLength()
Gets the length of this expression's value if it's an array, or indicates it's not an array
Returns
- the length of the array, or IDebugExpression.NOT_ARRAY if it's not an array
getDeclaredType() Method
public String
getDeclaredType()
If known, the declared type of the expression. May be null if the information
is not available. For example, in Java a variable may be an instance of java.lang.StringBuffer
but assigned to a variable of type java.lang.Object
Returns
- a string denoting the declared type of the expression.
getExpression() Method
public String
getExpression()
Gets the expression of this IDebugExpression, corresponding to its name in the current scope,
such as "localVariable.someField"
Returns
- the expression's name
getInterfaces() Method
public String
[] getInterfaces()
Gets the list of interfaces implemented by this object. This gets the full list, including interfaces
implemented by superclasses
Returns
- an array of strings representing the interfaces, null if there are no interfaces.
getValue() Method
public String
getValue()
Gets the Value of this IDebugExpression
Returns
- the expression's value
getValueType() Method
public String
getValueType()
Gets the type of the Value of this IDebugExpression, such as "int" or "java.lang.StringBuffer"
Returns
- the expression's type
isComplex() Method
public boolean isComplex()
IDebugExpressions are complex if they have children that are visible in the debugger
Returns
- if the expression has children
isEditable() Method
public boolean isEditable()
Gets whether the expression is editable or not.
Returns
- whether the expression is a value that can be edited - that is,
the debugger will be able to track down the variable again and set it
isError() Method
public boolean isError()
Returns whether this expression caused an error getting evaluated or not.
Returns
- true there was a problem evaluating the expression, such as incorrect syntax
false the expression had no problem evaluating
isStale() Method
public boolean isStale()
Gets whether the expression is stale or not.
Returns
- true if this expression's value has not been updated since
the last debugger event, like a step, setting a variable value, etc
isStatic() Method
public boolean isStatic()
Gets whether the expression is for a static member or not.
Returns
- whether the expression is a static member of a class.
