Interceptor > FileError

Static Properties

const int ABORT_ERR #

The file operation was aborted, probably due to a call to the FileReader abort() method.

from MDN

static const int ABORT_ERR = 3

const int ENCODING_ERR #

The file data cannot be accurately represented in a data URL.

from MDN

static const int ENCODING_ERR = 5

const int INVALID_MODIFICATION_ERR #

static const int INVALID_MODIFICATION_ERR = 9

const int INVALID_STATE_ERR #

static const int INVALID_STATE_ERR = 7

const int NO_MODIFICATION_ALLOWED_ERR #

static const int NO_MODIFICATION_ALLOWED_ERR = 6

const int NOT_FOUND_ERR #

File not found.

from MDN

static const int NOT_FOUND_ERR = 1

const int NOT_READABLE_ERR #

File could not be read.

from MDN

static const int NOT_READABLE_ERR = 4

const int PATH_EXISTS_ERR #

static const int PATH_EXISTS_ERR = 12

const int QUOTA_EXCEEDED_ERR #

static const int QUOTA_EXCEEDED_ERR = 10

const int SECURITY_ERR #

The file could not be accessed for security reasons.

from MDN

static const int SECURITY_ERR = 2

const int SYNTAX_ERR #

static const int SYNTAX_ERR = 8

const int TYPE_MISMATCH_ERR #

static const int TYPE_MISMATCH_ERR = 11

Properties

final int code #

The error code.

from MDN

final int code

final int hashCode #

inherited from Interceptor

Get a hash code for this object.

All objects have hash codes. Hash codes are guaranteed to be the same for objects that are equal when compared using the equality operator ==. Other than that there are no guarantees about the hash codes. They will not be consistent between runs and there are no distribution guarantees.

If a subclass overrides hashCode it should override the equality operator as well to maintain consistency.

docs inherited from Object

int get hashCode => Primitives.objectHashCode(this);

final Type runtimeType #

inherited from Interceptor

A representation of the runtime type of the object.

docs inherited from Object

Type get runtimeType => getRuntimeType(this);

Operators

bool operator ==(other) #

inherited from Interceptor

The equality operator.

The default behavior for all Objects is to return true if and only if this and other are the same object.

If a subclass overrides the equality operator it should override the hashCode method as well to maintain consistency.

docs inherited from Object

bool operator ==(other) => identical(this, other);

Methods

dynamic noSuchMethod(Invocation invocation) #

inherited from Interceptor

noSuchMethod is invoked when users invoke a non-existant method on an object. The name of the method and the arguments of the invocation are passed to noSuchMethod in an Invocation. If noSuchMethod returns a value, that value becomes the result of the original invocation.

The default behavior of noSuchMethod is to throw a noSuchMethodError.

docs inherited from Object

dynamic noSuchMethod(Invocation invocation) {
 throw new NoSuchMethodError(
     this,
     _symbolToString(invocation.memberName),
     invocation.positionalArguments,
     _symbolMapToStringMap(invocation.namedArguments));
}

String toString() #

inherited from Interceptor

Returns a string representation of this object.

docs inherited from Object

String toString() => Primitives.objectToString(this);
