IsReadOnly(Span)

Determines whether a text modification or deletion would be prohibited at span due to an IReadOnlyRegion

public:
 bool IsReadOnly(Microsoft::VisualStudio::Text::Span span);

public:
 bool IsReadOnly(Microsoft::VisualStudio::Text::Span span);

bool IsReadOnly(Microsoft::VisualStudio::Text::Span span);

public bool IsReadOnly (Microsoft.VisualStudio.Text.Span span);

abstract member IsReadOnly : Microsoft.VisualStudio.Text.Span -> bool

Public Function IsReadOnly (span As Span) As Boolean

Parameters

span

Span

The span to check.

Returns

Boolean

true if the entire span could be deleted or replaced, otherwise false.

Exceptions

ArgumentNullException

span is null.

ArgumentOutOfRangeException

The End property of span is greater than CurrentSnapshot.Length.

InvalidOperationException

TakeThreadOwnership() has previously been called, and this call is being made from a different thread.

IsReadOnly(Int32)

Determines whether a text insertion would be prohibited at position due to an IReadOnlyRegion.

public:
 bool IsReadOnly(int position);

public:
 bool IsReadOnly(int position);

bool IsReadOnly(int position);

public bool IsReadOnly (int position);

abstract member IsReadOnly : int -> bool

Public Function IsReadOnly (position As Integer) As Boolean

Parameters

position

Int32

The position of the proposed text insertion.

Returns

Boolean

true if an IReadOnlyRegion would prohibit insertions at this position, otherwise false.

Exceptions

ArgumentOutOfRangeException

position is negative or greater than CurrentSnapshot.Length.

InvalidOperationException

TakeThreadOwnership() has previously been called, and this call is being made from a different thread.

IsReadOnly(Span, Boolean)

Determines whether a text modification or deletion would be prohibited at span due to an IReadOnlyRegion

public:
 bool IsReadOnly(Microsoft::VisualStudio::Text::Span span, bool isEdit);

public:
 bool IsReadOnly(Microsoft::VisualStudio::Text::Span span, bool isEdit);

bool IsReadOnly(Microsoft::VisualStudio::Text::Span span, bool isEdit);

public bool IsReadOnly (Microsoft.VisualStudio.Text.Span span, bool isEdit);

abstract member IsReadOnly : Microsoft.VisualStudio.Text.Span * bool -> bool

Public Function IsReadOnly (span As Span, isEdit As Boolean) As Boolean

Parameters

span

Span

The span to check.

isEdit

Boolean

true if this check is part of an edit. false for a query without side effects.

Returns

Boolean

true if the entire span could be deleted or replaced, false otherwise.

Exceptions

ArgumentNullException

span is null.

ArgumentOutOfRangeException

The End property of span is greater than CurrentSnapshot.Length.

InvalidOperationException

public bool IsReadOnly (int position, bool isEdit);

abstract member IsReadOnly : int * bool -> bool

Public Function IsReadOnly (position As Integer, isEdit As Boolean) As Boolean

Parameters

position

Int32

The position of the proposed text insertion.

isEdit

Boolean

true if this check is part of an edit. false for a query without side effects.

Returns

Boolean

true if an IReadOnlyRegion would prohibit insertions at this position, otherwise false.

Exceptions

ArgumentOutOfRangeException

position is negative or greater than CurrentSnapshot.Length.
